Since 2000, more than 2,000 service members have suffered amputated limbs. DARPA?s breakthrough research with advanced prosthetic limbs controlled by brain interfaces is well documented, but such research is currently limited to quadriplegics. Practical applications of brain interfaces for amputees are still in the future.

A maverick neuroscientist believes he has deciphered the code by which the brain forms long-term memories. Teodore Berger, a biomedical engineer and neuroscientist at the University of Southern California in Los Angeles, envisions a day in the not too distant future when a patient with severe memory loss can get help from an electronic implant, MIT Technology Review reports.
University of California, Davis
Waterproof fabrics that whisk away sweat could be the latest application of microfluidic technology developed by bioengineers at the University of California, Davis.
Medical Product Manufacturing News
Researchers from the University of South Carolina strategically identified surfaces in hospital rooms that are likely to have bacteria on them and equipped them with copper surfaces. One out of every 20 U.S. hospital patients acquires a hospital-acquired infection (HAI). Such infections are estimated to cause 100,000 deaths each year in the United States, while adding an estimated $45 billion to the nation's healthcare tab. A number of recent studies suggest that copper, which has natural antimicrobial properties, could significantly reduce the numbers of such infections. For instance, a study published in the May issue of Infection Control and Hospital Epidemiology reported that the use of antimicrobial copper surfaces in hospital settings can reduce the number of HAIs by 58%. In contrast to the traditional cleaning procedures used within hospitals, the antibacterial effect of copper surfaces is permanent instead of episodic and not prone to antibiotic resistance. Stainless steel, which is commonly used in healthcare applications, does not have bactericidal properties.

Is a foolproof, smartphone-sized device that diagnoses diseases a pipe dream ? or can a $10 million competition turn the fiction into a lifesaver?
Medical Product Manufacturing News
Medical device applications likely weren't on the minds of the Microsoft engineers who developed the Kinect, which was introduced three years ago. But the video game peripheral has been hacked for an array of medical applications ever since it debuted. And the Kinect ONE represents a significant upgrade over its predecessor. The new platform comes equipped with an eight-core processor, 8 GB of RAM, and a 500 GB hard drive. Perhaps the device's sensor upgrades are most impressive: the device can detect millimeter movements and can even detect the heartbeat. All of this bodes well for its future medical applications?both in scope of them and in terms of user experience.
University of Illinois
University of Illinois at Urbana-Champaign researchers have developed a cradle and app for the iPhone (Android version in the works) that uses the phone?s built-in camera and processing power as a biosensor to detect toxins, proteins, bacteria, viruses and other molecules.
Medical Product Manufacturing News
The use of industrial-grade yarn in medical device applications has a long history. It has been customary to use the same fiber found in t-shirts and seatbelts in medical devices. This occurred because, until now, industrial fiber was the only source available. This trend continues as some medical device manufacturers and converters use industrial-grade fibers to keep cost down or they aren?t aware that medical grade fiber suppliers, like RxFiber LLC, exist.
Lawrence Berkeley National Laboratory
Most of the two million proteins in the human body can?t be crystallized without destroying them, so they can't be visualized. That's about to change. Berkeley Lab researchers and their colleagues have created a new way to model biological molecules using x-rays.
CNRS
A fluorescent dye that enables high-resolution (about 1 micron) 3D images of the cerebral vascular system has been synthesized by researchers at the Laboratoire de Chimie (CNRS) in France in collaboration with the Institut des Neurosciences (Universit? Joseph Fourier).

Optogenetic infrared light precisely illuminates neural pathways in the brain. A new tool that could help map and track the interactions between neurons in different areas of the brain is being developed by University of Texas Arlington assistant professor of physics Samarendra Mohanty.
University of Illinois at Urbana-Champaign
University of Illinois biophysicists at the Center for the Physics of Living Cells and the Institute for Genomic Biology have measured the molecular force required to mechanically transmit function-regulating signals within a cell.

UCLA Newsroom
When the hippocampus, the brain?s primary learning and memory center, is damaged, complex new neural circuits ? often far from the damaged site ? arise to compensate for the lost function, say life scientists from UCLA and Australia who have pinpointed the regions of the brain involved in creating those alternate pathways.

Even by the standards of the TED conference, Henry Markram?s 2009 TEDGlobal talk was a mind-bender. He took the stage of the Oxford Playhouse, clad in the requisite dress shirt and blue jeans, and announced a plan that?if it panned out?would deliver a fully sentient hologram within a decade. He dedicated himself to wiping out all mental disorders and creating a self-aware artificial intelligence. And the South African?born neuroscientist pronounced that he would accomplish all this through an insanely ambitious attempt to build a complete model of a human brain?from synapses to hemispheres?and simulate it on a supercomputer. Markram was proposing a project that has bedeviled AI researchers for decades, that most had presumed was impossible. He wanted to build a working mind from the ground up.

A harmless form of brain stimulation called transcranial random noise stimulation (TRNS) can help you learn math faster, researchers report.
Yale News
People provided with a real-time readout of activity in specific regions of their brains can learn to control that activity and lessen their anxiety, say Yale researchers.

Inventions that were discovered inadvertently often make for good stories. For instance, consider how a Raytheon engineer named Percy Spencer became known as the inventor of the microwave oven. While working on a radar research project after World War II, he stood in front of microwave-emitting vacuum tubes known as magnetrons. He reported feeling a tingling sensation and later noticed that the Mr. Goodbar candy bar he had in his pocket had melted. Then, working under the assumption that the magnetron equipment was the cause, his next inclination was to put some unpopped popcorn in front of the device. The result was the first microwave popcorn.
